 AB    Subcutaneous injection of Staphylococcal enterotoxin B (SEB) produced by
       Staphylococcus aureus, caused severe arthritis in DBA/1J mice which had
       been previously immunized with bovine type II collagen. The severity of
       this arthritis was dose dependent and prolonged joint inflammation with
       erosion of bone was observed. Anti- type II collage antibodies were
       detected in the serum of arthritic mice. Effector T cells against type
       II collagen were also detected by means of delayed type hypersensitivity
       in the skin. Moreover, a significant decrease in the ratio between T
       cells and B cells and an increase in the ratio between CD4+ cells and
       CD8+ cells was observed in spleen cells from arthritic mice.
       Prednisolone suppresses the induction and development of clinical signs
       of arthritis in mice. This evidence suggests that this experimental
       arthritis model may provide a means to examine the role of superantigens
       and the efficacy of pharmacological agents for the treatment of
       rheumatoid arthritis.
